A capacitor of capacitance is charged to a voltage and then isolated. An uncharged capacitor is then charged from , discharged and charged again; the process is repeated times. Due to this, the potential of the is decreased to , then the value of is:


Important Questions on Capacitance
A network of uncharged capacitors and resistances is as shown.
Current through the battery immediately after the key, is closed and after a long time interval is:



Six capacitors each of capacitance is connected as shown in the figure and initially all the capacitors are uncharged. Now a battery of is connected. How much charge will flow through the battery if the switch is on?

The equivalent capacitance between point and is

, then equivalent capacitance between and is

. If a potential difference of is applied across points and , then charge on the capacitor at steady state condition will be

The versus -plot for six identical metal plates of cross-sectional area is as shown. The equivalent capacitance between and is (adjacent plates are placed at a separation )
